R&S, Viavi team on certification of Foxconn O-RAN radio

Business news |

Rohde & Schwarz and Viavi Solutions are supporting the Auray OTIC and Security Lab in Taiwan with an integrated conformance certification test system for the latest O-RAN open radio units from Foxconn.

The lab is using a combined testbed including the Viavi TM500 O-RU Tester and the R&S SMW200A, FSW and VSE with the O-RU Test Manager from Viavi as a single point of control.

O-RAN is making radio access networks more open, disaggregated and flexible. Opening the network architecture can foster innovation, accommodate individual needs and enhance network efficiency, but interoperability and certification is a key issue. The Open Testing and Integration Centres (OTIC) worldwide cooperate with the O-RAN Alliance in the O-RAN Certification and Badging Program as a key mechanism to ensure confidence in O-RAN solutions within the industry.

The certification of an O-RU of the RPQN series from Foxconn, the world’s largest electronics manufacturer, was completed according to O-RAN specified processes and procedures as defined by the O-RAN Alliance. As well as making Apple’s iPhones and iPads and moving into making electric cars, Foxconn is now making radio equipment. 

Foxconn developed the RPQN series 5G NR Radio Units (O-RU) to be fully compliant to O-RAN Alliance standards. The Foxconn 4T/4R small cell radios are covering 5G NR bands n79, n78, n77 and n48 for indoor applications. The design has completed the extensive 3GPP and O-RAN compliance testing and is also certified in most major regions for CE, FCC, TELEC and NCC in Taiwan.

The O-RU verification followed the O-RAN fronthaul conformance test specification defined by WG4, including the Control, User, and Synchronization plane (CUS-Plane) and the Management-plane (M-Plane). WG4’s objective is to deliver open fronthaul interfaces, in which interoperability between Distributed Unit (DU) and Radio Unit (RU) from multiple vendors can be realized. To add independent peer-review, Auray OTIC and Security Lab obtained TAF ISO/IEC 17025 approval for O-RAN test results and follows ISO/IEC 17065.
